7 2 Claims. (01. 95-47) Our invention relates to a new and usefulimprovement in a photographic print washing receptacle in which thephotographic prints may be deposited and whereby the prints after beingdeposited in the washer may be subjected to a cleansing bath while atthe same time they are maintained in an agitated state.

Another object of the invention is the provision of a photographic printwashing machine so arranged and constructed that the liquid containedwithin the washing pan is always being agitated and replenished andrenewed.

Another object of the invention is the provision of a photographic printwasher embodying a liquid container having an outlet delivery pipeconnected therewith for continuously draining liquid therefrom andprovided with an inlet pipe for continuously delivering liquidthereinto, the delivery of the liquid into the container being such thatthe liquid contained in the container is agitated at the bottom thereofand also at the top thereof thus preventing collection of sediment in,the pan and assuring an outflow of the sediment which is washed off ofthe prints.

Another object of the inventionis the provision of a photographic printwashing machine which will be highly emcient in use, simple inconstruction, compact and light.

Another object of the invention is the provision of a photographic printwashing device so arranged and constructed that sprays of Water may bedelivered thereinto slightly below the water level so as to thoroughlyagitate the prints which may be floating on the Water and prevent thesame from becoming dry on their outer face.

Other objects will appear hereinafter.

It is recognized that various modifications and changes may be made inthe detail of structure illustrated without departing from the inventionin itself and it is intended that such variations and modificationsshall be embraced within the claims which form a part hereof.

Forming a part of this specification are drawings in which,

Fig. 1 is a top plan view of the invention,

Fig. 2 is a view taken on line 2--2 of Fig. 1,

Fig. 3 is a sectional view taken on line 33 of Fig. 1, slightly reduced,

Fig. 4 is a fragmentary perspective view of one end of the invention,

Fig. 5 is a fragmentary view taken on line 55 of Fig. 3, slightlyenlarged.

In the drawings we have shown the invention comprising a liquidcontainer embodying the oppositely disposed side walls l0 and II and the2 oppositely disposed end walls l2 and I3 and the bottom [4. An outletdrain pipe I5 is mounted on the wall 13 so as to communicate with theinterior of the receptacle. It will be noted that the side walls II andID are tapered in height being higher adjacent the end wall l3 thanadjacent. the end wall [2. We have found that on a pan in which thedistance between the end walls 12 and I3 is twenty-four inches adifference in the height of the side walls at their opposite ends wouldbe approximately one-half inch. For instance, if the distance betweenthe outside faces of the end walls l2 and I3 is twenty-four inches theheight of the side walls l0 and II at the end wall l2 would be fourinches and their height at end wall l 3 would be four and one-halfinches, this variation in height being a gradual tapering. Consequently,this forms the pan or receptacle deeper at one end than it is at theother. However, when in use the upper edges of the side walls [0 and Hwould be extended parallel to a supporting surface such as a table onwhich the receptacle would be positioned. This is effected by mountingon the under face of the bottom I4 a supporting bar 34 which willelevate one end of the receptacle from the table or support on which itis positioned, and, in the size referred to, this elevation would beone-half inch. Thus the upper edges of the side walls would be parallelto the supporting table and yet the bottom of the container would beslanting toward the end l3.

Extended transversely of the receptacle or pan in spaced relation to thewall I3 is the partition l6 having at its lower edge spaced-apartnotches or openings I1 formed therein, the lower edge thereof beingangularly turned to provide the tongues l8 which are welded or otherwisesuitably secured to the bottom l4. One end of the partition I6 isangularly turned as clearly shown in Fig. 1 so that it engages thecorner 2| of the receptacle or pan. This angularly turned portion I9 hasthe angularly turned flange point 20 which engages the inner surface ofthe receptacle or pan at the corner and which is soldered, welded orotherwise suitably secured thereto. The opposite end of the partition I6is provided with the angularly turned flange point 22 which engagesagainst and is welded to the inner surface of the side wall l0. Thusthere is provided within the container or pan, adjacent one end thereof,a chamber 23.

Mounted on the partition l6 aresupporting straps 24 in which is formedthe slot 25 through which is projected the bolt 26 on which is threadedthe wing nut 21. The lower end of the straps 24 are angularly turned toprovide the cradle 24A in which rests the inlet delivery spray pipe 28having an end thereof closed by the cap 29. This closed end is angularlyturned to provide the substantially circular formation 30 in which areformed the spaced-apart openings 3!. These spaced-apart openings-3| arenormally below the water level"33.. Formed in the main body of the pipe28 are outlet openings 32 which are spacedapart and which are normallybelow or partially below the water line 33 so that water issuing out ofthe outlet openings 32 will issue as ,a spray which will serve toagitate the water adjacent its water line and keep the top of "the waterwhich is contained within the pan ina state of agitation and movementsothat printsplaced in the water will be agitated and prevented fromdrying on their upper surfaces. 7

The pipe 28 is connected by the conduit 46 to a faucets which isconnected to asuitablesouroe of water under pressure. .openedthe waterwill flow into the pipe .28 and outwardly through :the'openings 32 and3!. -Com- -partment23 will of course fill with this water When thefaucet is to the water level which may be maintained by adjusting theinlets to the outlets. When photographic printsare placed in the waterin the receptacle or pan the-heavier solution washed .from thephotographic prints will of course be precipitated. This heaviersolution will not be permitted to accumulate on the bottom .14 of thepan because thesprays issuing from the outvlet openings 31 maintain thiswater in a constant state of agitation and prevents any sedimentaccumulating onthe bottom. This heaviermaterial will of course passthrough the opening 1-,!

into the chamber 23 where it flows outwardly j surface and at its uppersurface. .It is believed obvious that the pipe 28 may be adjustedupwardlyaand downwardly because of the presence of the slot in thesupporting strips 24 thus accommodating the device to various containersor receptacles which may have different water levels without in anymanner interfering with the normal operation and functionings of thesprays'of'water issuing from the outlet openings 32. :By this adjustmentalso the pipe 28 may be r 4 moved upwardly or downwardly water leveldepending upon the desires of the operator andthe effect which hedesires'to produce.

What we claim as new is:

1. A print washer of the class described, comprising: a liquidreceptacle embodying oppositely disposed side walls, oppositely disposedend walls and abottom; a transverselyxextended'partition .mountedin saidcontainer adjacent one of said end walls; a pair 'of hangers mounted onone face vof said partition; an inlet delivery pipe supported on saidhangers and extending longitudinally of said partition; an angularlyturned closed end on said'del-ivery pipe turned into substantially aacircular formation and projecting downwardly from said delivery pipe,said angularly turned end having outlet-openings formed therein and.said pipe having outlet openings formed therein;

the outlet openings in .said pipe being positioned above the outletopeningsin said angularly turned portion.

2. A print washer of the class described, comprising: aliquid-receptacle embodying oppositely disposed side wa'lls,.oppositelydisposed end walls and .abottom; a transversely extended partitionmounted in said container adjacent one ofsaid end walls; apair ofhangers mounted on one face 7 of said partition; ,aninIe't delivery pipesupported on said hangersand extending longitudinally of said partition;an .angularly turned closed end on said delivery .pipe turned'intosubstantially a circular formation and projecting downwardly from saiddelivery pipe, said angularly turned .end having outlet openings formedtherein and said pipe having outlet openings formed therein,

the outlet openings in saidtpipe beingpositioned above theoutletopenings in said angularly turned portion; andmeans for adjustingsaid hangers vertically on said partition for. adjusting the positionofsaid inlet delivery pipe relatively .to the bottom of said container.
